What condition leads to the formation of a black hole after core collapse?
Answer
The force of gravity overwhelming even the degeneracy pressure provided by neutrons.
The final state of a collapsing stellar core hinges on mass. If the core remnant possesses enough mass, the relentless force of gravitational contraction becomes overwhelmingly powerful. This gravitational crush surpasses the internal outward pressure that neutrons can exert, known as neutron degeneracy pressure, which is the force that supports a neutron star against further collapse. When gravity wins this ultimate battle, the collapse continues without cessation, resulting in the formation of a region of spacetime where gravity is inescapable—a black hole.
